So if you're from an arid world, you can live on any arid world. If you're from a methane world, you can live on any methane world. Karst worlders can settle any karst world, and so on and so on.
I think that makes things too easy.
I'd like to propose a new variable to determine what planets you're able to settle, Base Pairs and another that's mostly for flavour, that every species (save for anomalies) in your galaxy shares: Nucleic Acids.
Forgive me if I get some of the science wrong, I'm no biochemist, lol
On Earth, we use five paired nucleobases for our DNA: Adenine, which pairs with Thymine in DNA or Uracil in RNA, and Guanine, which pairs with Cytosine. We'll call this ATGC.
If you make a species with ATGC, they would only be able to produce Food on planets that are also ATGC-based, because this is what your proteins are formed from--without compatible proteins, they can't eat the local flora or fauna, and either have to import Food in from their other colonies (eg you would make a farm world that produces a surplus of Food that can be exported throughout your empire), or else they could buy Food on the Galactic Market.
This wouldn't necessarily affect the habitability percentage, as you can still live on a planet with alien DNA, but it'll make your life harder and you'll have to think more carefully about where you settle. Even Devouring Swarms would have to think twice about devouring an incompatible planet! (jk they'd still eat you, but maybe their fleets could become weaker afterwards because they don't gain any nourishment from you)
Other potential DNA bases could include:
DNA uses paired nucleobases, in addition to a backbone of sugar: DNA uses deoxyribose, but other alternatives are possible, such as:
I think this would result in some great storytelling possibilities, and it also serves to make the game a little bit harder.... if you want it to be.

Base Pairs
On Earth, we use five paired nucleobases for our DNA: Adenine, which pairs with Thymine in DNA or Uracil in RNA, and Guanine, which pairs with Cytosine. We'll call this ATGC.

Even Devouring Swarms would have to think twice about devouring an incompatible planet! (jk they'd still eat you, but maybe their fleets could become weaker afterwards because they don't gain any nourishment from you)
Other potential DNA bases could include:
- Xanthine, which binds to Cytosine (thus an alternative to Guanine)
- Hypoxanthine (another Guanine alternative)
- Diaminopurine (an alternative to Adenine)
- or any combination of the above
- All - all habitable planets share your DNA base pairs, just as in vanilla Stellaris
- High - 75% of habitable worlds share DNA
- Mid - 50%
- Low - 25%
Nucleic Acids
DNA uses paired nucleobases, in addition to a backbone of sugar: DNA uses deoxyribose, but other alternatives are possible, such as:
- PNA (peptide nucleic acid)
- GNA (glycol nucleic acid)
- CeNA (cyclohexene nucleic acid)
- HNA (1,5-anhydrohexitol nucleic acid)
- FANA (fluoro arabino nucleic acid)
- Z-DNA (just DNA, but the double-helix is shaped like a mirror image)
- A-DNA (just DNA, but the double-helix is shorter and more compact)
- View all other alien life as exotic curiosities to be catalogued (thus a boost to your relationship)
- View all other alien life as aberrations to the natural order (thus a penalty to your relationship)
- Materialists that don't even consider you to be life at all, and require SERIOUS convincing
I think this would result in some great storytelling possibilities, and it also serves to make the game a little bit harder.... if you want it to be.
